Radiological markers of CSF α-synuclein aggregation in Parkinson's disease patients.
Article in NPJ Parkinson's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Alpha-synuclein (αS) aggregation is a widely regarded hallmark of Parkinson's disease (PD) and can be detected through synuclein amplification assays (SAA). This study investigated the association between cerebrospinal fluid (CSF) radiological measures in 41 PD patients (14 iPD, 14 GBA1-PD, 13 LRRK2-PD) and 14 age-and-sex-matched healthy controls. Quantitative measures including striatal binding ratios (SBR), whole-brain and deep gray matter volumes, neuromelanin-MRI (NM-MRI), functional connectivity (FC), and white matter (WM) diffusion-tensor imaging (DTI) were calculated. Nine LRRK2-PD patients were SAA-negative (PD-SAA-). PD-SAA+ patients showed lower whole-brain gray matter, putamenal, brainstem, and substantia nigra volumes, reduced FC in the left caudate, and lower fractional anisotropy in the left fronto-occipital fasciculus compared to PD-SAA-. Taken together, αS aggregation was observed in iPD, GBA1-PD, and 38% of LRRK2-PD patients, and this was associated with reduced regional brain volumes, altered caudal FC, and SBRs. These changes were less pronounced in PD-SAA-, possibly suggesting a milder neurodegenerative process.
